It’s gotta be the shoes

We (Tom and Peter) got new shoes called FiveFingers from Vibram which are unlike any other type of shoe you have probably ever seen before. They have separate sections for each of your toes and they also have cuts in the bottom to allow for added flexibility and so that when the shoe bends the cuts open and provide add traction, so when you are running flat out you have better turning and acceleration capabilities. These were created because running in bare feet is supposed to be good for them unless you step on glass or something. These are for imitating bare feet while still keeping your foot uncut.

Tom wears them everyday and thinks they’re absolutely amazing and the best shoes he has ever worn. Peter thinks he hasn’t worn them as much as Tom so he hasn’t had time to get a solid opinion but he still likes them quite a bit so far.

This is a video from wired.com, and it is better at explaining how they work than we are.
